Page 303: Section 14 Commissioning And Maintenance Of The Fault Clearing System
The periodicity of all tests depends on several factors, for example the importance of the installation, environmental conditions, simple or complex equipment, static or electromechanical IEDs, and so on. The normal maintenance practices of the user should be followed. However, ABB's recommendation is as follows: Every second to third year Transformer protection RET670 2.2 ANSI...

ABB protection IEDs are preferably tested by aid of components from the COMBITEST testing system or FT test systems described in information B03-9510 E. Main components are RTXP 8/18/24 test switch usually located to the left in each protection IED and RTXH 8/18/24 test handle, which is inserted in test switch at secondary testing.

Page 315: Repair Instruction
An alternative is to open the IED and send only the faulty circuit board to ABB for repair. When a printed circuit board is sent to ABB, it must always be placed in a metallic, ESD- proof, protection bag.

15.4 Repair support If an IED needs to be repaired, the whole IED must be removed and sent to an ABB Logistic Center. Please contact the local ABB representative to get more details. 15.5 Maintenance The IED is self-supervised.
